Polymarket's April trading volume fell 8.9% to $10.2B as rivals like Kalshi gain ground, raising questions about the platform's U.S. expansion and regulatory hurdles.
Prediction market Polymarket recorded its first monthly trading volume decline since August, with April's activity dropping 8.9% to $10.2 billion compared to March's $11.2 billion, according to Dune Analytics data. The decline comes as the company attempts to re-establish itself in the U.S. market amid mounting competition and regulatory pressures.
While Polymarket saw a pullback, competitor Kalshi surged ahead, reporting a 13% increase in trading volume to $14.8 billion in April. Overall, the prediction market sector grew 12.4% month-over-month, reaching $29.8 billion in total trading volume. Polymarket's loss of market share highlights the increasingly crowded field, with platforms like Prophet and MoonPay debuting AI-driven trading tools to attract users.
Regulatory Scrutiny and U.S. Expansion
Polymarket's challenges extend beyond competition. The platform has faced heightened regulatory scrutiny in the U.S., where lawmakers have raised concerns about insider trading on prediction markets. In March, Senator Elizabeth Warren and over 40 Congressional representatives called on the Commodity Futures Trading Commission (CFTC) to crack down on government officials who allegedly use such platforms for financial gain in politically sensitive markets.
Polymarket exited the U.S. in 2022 as part of a settlement with the CFTC, which barred the platform from servicing American users on its global exchange. In December 2025, the company launched a U.S.-specific app, but the platform remains isolated from Polymarket's broader liquidity pool. Competitors like Kalshi, meanwhile, have been expanding aggressively in the U.S., raising questions about Polymarket's ability to close the gap.
What’s Next?
Polymarket's efforts to regain momentum come as the prediction market sector continues to evolve. The introduction of AI-powered tools, like Prophet's AI counterparty model and MoonPay's trading strategy platform, reflects a shift toward more sophisticated offerings. However, regulatory uncertainty remains a significant obstacle, not just for Polymarket but for the entire industry.
With lawsuits from officials like Wisconsin Attorney General Josh Kaul targeting platforms for alleged violations of state laws, the regulatory landscape will likely shape the future of prediction markets. For Polymarket, balancing compliance with innovation will be critical as it seeks to regain its footing in the competitive U.S. market.
